APPARATUS FOR HEATiNG 'l'HERMOPlLES.

SPECIFICATION forming part of Letters Patent No. 563,262, dated July 7, 1896. Application filed March 8, 1892. Serial No. 424,167. (lie model.)

To all whom it may concern.-

Be it known that I, EDWARD N. DICKER- SON, of the city, county, and State of New combinationof heated gas and air under pressure.

My invention will be readily understood from the accompanying drawings,inwl1ich' Figure 1 represents a vertical cross-section through my apparatus, and Fig; 2 a vertical longitudinal section through the same.

A represents, generally, the inclosin g chamber,.and B the thermopiles, which are preferably of the form shown, though any other suitable thermopile may be employed. As arranged, they project through the casing A, being heated within the same. This easing may be of any suitable construction, but shouldbe so arranged as to insulate the elements, one from the other. Any suitable arrangement of brick or tiles can beemployed. This heating-chamber connects with a chimney C, through which the products of combustion escape. with a heating coil or coils in which the entering gas or air and gas is heated by the escaping products of combustion.

As shown, F represents/the air-pipe connecting with the blower or air-pump D; G, the gas-pipe communicating with the, gas

ump E. These coils should be made of suitable length to practically absorb the waste heat of combustion. Asshown, the gas and air are heated independently, uniting in the pipe ll,their relative proportions being controlled by thevalves K K. They are then burned in the burner L, together with the addition of the heated air passing by the pipe M, controlled by valve N, and being delivered through the pipe 0, beneath the burner This chimney is provided 'L. As shown, the burner and air supply is duplex, being intended toheat two facing elements l3 B, which are, of course, provided with the ordinary electrical connections P. P.

R represents the lighting-door, and an additional supply of cold air maybe admitted beneath the burner, if desired. I prefer, however, the arrangements shown.

Obvi0usly',care must be taken in the regulation of the valves K K with relation to the speed of movement of the gas and air to be burned, to prevent an explosion within the pipe H. This is a matter well known by those skilled in the art.

It is obvious that one blower .and pipemay be used for heating the gas and air, but the.

danger of explosion is thereby increased, and I prefer the arrangement shown.

I may, if I desire, heat either the gas or air independently, but, manifestly, it is preferable to heat both, so as to get the best possible eifect.

It is obvious that the arrangement of the parts is immaterial, and that the thermopiles need not project outside of the furnace, unless it is so desired, though the arrangement shown gives the best results.

hat I claim as my invention, and desire to secure by Letters Patent, is- 1. The combinationoftl1ecasingA,through which the thermopile elements project, the

said casing containing in itself, or a c0ntinu-- ation thereof, apparatus for heating the gas burned beneath the thermopile and a suitable burner for burning the heated gas, substantially described.

2. The combination of the casing A.,'through which the thermopileelements project, the said casing containing in itself, or a continuation thereof, apparatus for heating the gas and air burned beneath the thermopile and a suitable burner forburning the heated gas,

substantially as described.

3. The combination of the blowcrsD E, the heating-pipes F F, the casing containing the same, suitable burners for burning the heated.

gas and air andthe thermopiles B B, substantially as described.

In testimony whereof I name to this specification i1 two subscribing witnesses.
